adu-corrections-flow

adu-corrections-flow is a skill for Claude Code, Codex from mikeOnBreeze/cc-crossbeam. It costs 168 tokens per session (2,913 once invoked), scanned A, original, MIT.

A workflow for examining correction letters on accessory dwelling unit permits. An accessory dwelling unit, or ADU, is a smaller home on the same property as a main home.

In plain words
What is it for?
Use it to review an ADU corrections letter, identify the affected drawing sheets, research building rules, group correction items, and produce questions for the contractor.
Why use it?
It turns vague permit feedback into specific, code-informed questions by checking the correction letter, plan sheets, and relevant state and city requirements.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

adu-corrections-flow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ADU Corrections Flow

Overview

Analyze ADU permit corrections and generate informed contractor questions. This is the first skill in a two-skill pipeline:

  1. adu-corrections-flow (this skill) — reads corrections, researches codes, categorizes items, generates questions
  2. adu-corrections-complete (second skill) — takes contractor answers + these research artifacts, generates the final response package

This skill coordinates three sub-skills through a 4-phase workflow and stops after producing contractor_questions.json.

Sub-skills used:

Skill Role When Used
california-adu State-level building codes (CRC, CBC, CPC, etc.) Phase 3A — offline, 28 reference files
adu-city-research City municipal code, standard details, IBs Phase 3B (Mode 1: Discovery) + Phase 3.5 (Mode 2: Extraction) + optional Mode 3 (Browser Fallback)
adu-targeted-page-viewer Sheet manifest + on-demand plan viewing Phase 2 + Phase 3C — PDF extraction + vision

Key principle: Research happens before contractor questions. Questions informed by actual code requirements are specific and answerable in seconds. Vague questions waste the contractor's time.

Inputs

Input Format Required
Corrections letter PDF or PNG (1-3 pages) Yes
Plan binder PDF (the full construction plan set) Yes
City name String (extracted from letter if not provided) Auto-detected
Project address String (extracted from letter if not provided) Auto-detected

Outputs

All outputs are written to the session directory (e.g., correction-01/).

Output Format Phase
corrections_parsed.json Structured correction items Phase 1
sheet-manifest.json Sheet ID ↔ page number mapping Phase 2
state_law_findings.json Per-code-section lookups Phase 3A
city_discovery.json Key URLs for the city's ADU pages Phase 3B
sheet_observations.json What's on each referenced plan sheet Phase 3C
city_research_findings.json Municipal code, standard details, IBs (extracted content) Phase 3.5
corrections_categorized.json Items with categories + research context (the main handoff artifact) Phase 4
contractor_questions.json UI-ready question form data Phase 4

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
